Hmm. I'm getting this, too. Do you get crashes from a process called "PosterBoard"? If I open up the Console app and look at Crash Reports, I see more than 20 of them in quick succession over a minute or so after I launch the simulator. I've reported this as a bug via the Feedback Assistant.

This happened to me and it was because I hadn't set the frame on the AVRoutePickerView: let routePickerView = AVRoutePickerView() But it showed up as soon as I gave it a frame (in this case from the outlet to my UIView): let routePickerView = AVRoutePickerView(frame: routePickerButton.bounds)
